About

A bit about me

I'm a software engineer who builds reliable backend systems, APIs, and cloud-native services — with a soft spot for where software meets hardware, and lately, agentic AI.

My path into software started early: a 10-unit computer science major in high school (95% average), then building my first MQTT server and a microcontroller-driven smarthouse the year I graduated. Before committing fully to software, I spent about two years doing electrical work in gas stations and large facilities — hands-on, safety-critical, detail-driven.

Today I'm an AWS Certified Developer Associate and comfortable across the stack — Java/Spring Boot, React, AngularJS, and Arduino/C++ when a project needs hardware. First place at one hackathon, second at another (EcoHack), a department-best capstone, and a spot in the Hasoub Labs 2026 Accelerator. Most recently, I've gone deep on agentic AI — building Python agents and automation workflows on the frontier models.

Open to backend, full-stack, cloud engineering, and embedded roles.
What I Do

How I can help

Backend APIs & Services

ASP.NET Core and Spring Boot APIs, background workers, and integrations. SQL Server, Postgres, REST and gRPC — designed for testability, traced for observability.

Cloud & DevOps

AWS (S3, EC2, Lambda, DynamoDB) for production workloads. Containerized with Docker, orchestrated where it earns its keep. CI/CD pipelines that catch regressions early.

Full-Stack & Hardware

React / Angular front ends backed by .NET or Node. Mobile and desktop too — and Arduino/C++ microcontroller work when a project reaches into the physical world.

Journey

How I got here

From a microcontroller smarthouse to cloud-native systems and agentic AI. Tap any milestone for the full story.

  1. One of the most demanding high-school tracks — a 10-unit major combining computer science with software and systems engineering. It covered programming fundamentals, data structures, and algorithms, and gave me my first hands-on experience writing C#.

  2. The year I finished school, I set up my first server using the MQTT messaging protocol to connect devices — then designed and built a smarthouse system around it. Microcontrollers programmed in C, wired to sensors and relays I assembled myself.

    It was my first real taste of making software and hardware talk to each other, and it set the direction for everything that followed.

  3. Around two years of hands-on electrical installation and maintenance at gas stations and large industrial sites — reading schematics, wiring systems, and troubleshooting faults under real-world constraints.

    The safety-first, measure-twice discipline from that work still shapes how I approach engineering today.

  4. A full software engineering curriculum — algorithms, databases, distributed systems, and web and mobile development — alongside the team projects and competitions below.

  5. Won first place at a hackathon with a team-built application — designing, building, and presenting a working product against the clock. Earth Keepers (JavaFX) was one of those efforts.

  6. A Spring Boot microservices backend, a React front end, deployed on AWS EC2, with an Arduino device in C++ feeding live data into the system.

    Awarded first place in the software engineering department — my favorite blend of cloud, web, and hardware in one project.

  7. Built and presented an environmentally focused solution at EcoHack, taking second place.

  8. Validates hands-on experience building and maintaining applications on AWS — S3, EC2, Lambda, and DynamoDB.

  9. Set up a dedicated workspace and committed to intensive, self-directed agentic AI engineering — working daily across the frontier model platforms (Claude, Google Gemini, and ChatGPT) to design, build, and ship real systems.

    The focus is production-minded patterns rather than demos: Python agent workflows, tool use, multi-step orchestration, and LLM-driven automation — turning today's models into software that actually does the work.

  10. Since October 2025 I've been teaching high-school students how to use AI as a genuine learning tool rather than a shortcut — using it to deepen their understanding instead of replacing it.

    Security and privacy are the top priority in every lesson: what data is and isn't safe to share, how to spot and verify AI mistakes, and how to use these tools responsibly and ethically.

  11. This one started at home. With our baby on the way, I built Baby Wish List for my wife — and it grew into a full, public app that any expecting or new parent can use.

    Before the birth it's a shareable gift registry: add everything you need — a crib, toys, the essentials for the baby-shower — and share the list publicly so family and friends can claim a gift and mark what they're bringing. No duplicates, nothing forgotten.

    When you mark the baby as born, the app opens a baby diary for daily care. Loggable events:

    • Breastfeeding
    • Bottle feeding
    • Milk pumping
    • Diaper changes
    • Sleep
    • Bath time
    • Medications
    • Growth measurements

    It also tracks what the mother needs and the household necessities, and flags anything out of stock — so a store run starts with a ready shopping list of everything to restock and mark back in.

    You can add more than one child and share each child with the other parent or a caretaker — and share a specific list publicly with a professional, like a doctor or a breastfeeding advisor, so they can follow along. That last part is exactly what I used it for.

    Shaped in Lovable, then designed and built locally with vibe coding — with security and scalability kept front and center throughout.
